Hey, is it possible to control the exchange rate on outgoing invoices? If I invoice in dollars the app automatically gives me the exchange rate on the day of issue but it won’t let me adjust that.

I can't remember it offhand but the exchange rate is the exchange rate. It's only an indicator the real exchange rate is what the banks charges you on the day the money hits your bank account.
We take the fx transaction and create a bill for the bank charge, work out if there was an FX gain or loss. If a gain then we run the tax on that. We then update all your management accounts. Automatically.

Tell me exactly what you're doing.
Either way you can't pick the exchange rate - the markets define the exchange rate.

that's the banks rate on the day.
